Popular Anime in Japan: A Deep Look into the Series Japanese Fans Truly Love

Hello, I’m the owner of Chill Greenhouse, a Japan-based proxy purchasing service, and I currently live in Japan.
Living in Japan allows me to experience anime trends as they truly exist here—not just online, but in everyday life, physical stores, limited-time events, and real-world collaborations happening across the country.

Japan is the birthplace of anime, and its influence goes far beyond entertainment. Anime in Japan is not simply something people watch; it is deeply woven into culture, advertising, fashion, and daily life. From children to office workers, anime characters appear everywhere—on trains, in convenience stores, on product packaging, and at large-scale exhibitions.

For fans living outside Japan, it can be difficult to understand which anime are genuinely popular inside Japan, because overseas popularity and domestic popularity do not always align. In this article, I’ll introduce anime series that are truly popular in Japan and explain why they matter—especially for fans and collectors looking for authentic Japanese merchandise.

Anime Culture in Japan: More Than Just Entertainment

In Japan, anime is mainstream culture. Popular series regularly collaborate with:

• Convenience stores such as 7-Eleven, Lawson, and FamilyMart
• Fashion and streetwear brands
• Food and beverage companies
• Pop-up cafés, exhibitions, and theme parks
• Public transportation, including trains and buses

These collaborations often result in limited-edition items that are only available in Japan and only for a short period of time. Because of this, many highly desirable anime goods never reach international markets.

Living in Japan makes it clear that anime popularity here is measured not only by streaming numbers, but also by how often a series appears in real-world collaborations and physical retail spaces.
